MACHINE FOR rnonucine srmnn P FF s."

T 0 all whom it may concern:

Be it known that L'CALVIN M. ANDERSON,

a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new,

and useful Improvements in Machines for Producing-Spiral Puifs,"of which the following is a'specification; I

This invention relates to an improved machine for producing spiral uff or gath- Withthese and other'objects in viewas will appear as the description proceeds, the

invention accordingly consists in the novel features of construction, combination of ele 'ments and arrangements of parts hereinafter to be fully described and to have the scope thereof pointed out in the appended claims. Y

In the accompanying: drawing, forming a part of this specification, and in which similar characters of reference denote like and corresponding parts: g Figure 1 v 's atop plan vlew' of a gather forming machine comprising the present invention, parts being broken away to disclose theunderlying structure. 7

Fig. 3 is a detailed transverse sectional view disclosing more particularly the mannor of transmitting motion from one of said sections to an adjoiningsection.

Fig. 4 is a detailed perspective View .of the upper end of one of the post members.

Fig. 5 is a perspective view of one of the p I braiding elements, and,

spring holding device 6. by practice that it is desirable tosquare the "fabric material be' gathered', shirred or i Specification of Letters Eatent. Patented Feb. 22, 1921 I puffed to produce certain artistic effects," and heretofore this process has been largely effected-by tedious hand work and which of necessity has involved considerable expense ineffecting the production-thereof; The

present invention aims to produce *a machinewhereby these, effects may be quickly and economically produced without detracting in any way; from the general artistic and pleaslng appearance of the same. I

To this end the present invention contemplates the provision of a pluralityof frames.

which are designated by the numeral 1. These frames are of substantially rectangular configuration andare. disposed tolie side by side and to be supported by means of 5' parallel angle members 2, from which the frames are freely removable. The number of frames employed is of'course governed by the width of the :material to bev acted" upon an'dtherefore one or more framesimay be utilized. Mounted for rotation upon said frames is a plurality of vertically up standing posts-3, which are provided with lower circular portions and with upper square 7 extremities 4, the latter projecting above the 1 tops 5 of said frames. The upper ends of.

said posts are provided with spring elements 6, which are adaptedto.:receive aplurality of prong members 7. :The posts 3 are disposed in equally spaced relation and inoperation a layer of fabric materialto' beacted upon is placed: upon the upper-squared ends oflthe post's and in engagement with the prongs of the members 7, which lattena're detachablybut rotatably carried bythe upper ends of said "posts": Y By-rotating the 2- posts substantially a complete cycleof movement,-the spiral puff v.8 formed upon the ma! terial 9 is, produced, and this effect is maintained by placing upon the material 9 a lining 10. Then by bending the prongs of the members 7 downwardly upon the lining, the puff effect will thus be preserved. The

material may then be removed from engagement with the posts by simply removing the prong members 7 from en agement with the t has been found upper ends of the posts 3 in order that when the latter are rotated, the corners formed by the squared ends will engage with the ma-' terial 9 and assist inimparting the neces sary spiral movements thereto. V

In order to simultaneously effect the rotation of the posts3, use is made of a gearing 11. This gearing may be one of many equivalent and obvious structures but for purposes of illustration, each of the lower ends,

of the posts 3 is equipped with a gear 12, the

latter being adapted for engagement with a plurality of alternately and reversely threaded worms 13 which are carried upon a longitudinally extending shaft 14 extending centrally through each of-the frame sections 1. It will beseen that by rotating the shafts V 14, rotary movementin identical directions will beimparted to the posts-'3 so that, the

act upon the material 9, in the latter may above recited manner.

In order to rotate all of the shafts simultaneously, each of said frames is equipped witha transversely --journaled shaft 15, the latter being provided at one end with a protruding squared extremity 16, and at its other end with a socketed portion 17, the portion ,17 terminating within the frame 1 and in' alinement with an opening ducing artistic puff effects uponfabric or,

other similar materials,and the structure 18, formed in the side wall of theframe. Through this arrangement of parts, it will be obvious that a multiplicity ofthe frames openings 18 and intothe socketed portion 17 o adjoining shafts. Thus, all-of.the trans--.'

verse shafts willbe connectedfor uniform rotational movement: Each'shaft 15 is also provided with a worm 19, which is arranged for meshing engagement with -a cooperative worm gear 20'carriedupon one end of the longitudinally extending'shaft 14. In this I manner the rotation of oneof; the transverse: shafts 15' will effect. simultaneous rotation of all of the same, and their. rotary movement, in turn, is imparted to the longitudinally extending, shaftsl, and thence by means of; the gearing .11 to the posts 3.

From'the fore oing description, taken in connection with t e accompanylng drawing, 7

it will be apparent that there is-provided mechanism. for quickly and "efficiently prois such as to enable the puff effects to be produced simultaneously .over the ,full area of the material; Through the'provision of the removable prong members 7 the puff effects adapted to materials of varying proportions.
